Portfolio.com media blogger Jeff Bercovici posted a short item about one of the panels yesterday afternoon; later that evening, the story had disappeared.

It should never have run in the first place, Portfolio.com managing editor Daniel Colarusso tells me. That’s because Portfolio magazine was a sponsor of the event (editor in chief Joanne Lipman moderated one panel; Washington editor Matt Cooper moderated the one that Bercovici wrote about) and is honoring its no-press rules.

Again, it’s Quadrangle’s conference, and they can run it however they’d like. But it seems particularly ironic that the one story that did get published, then pulled, was about a panel of professional communicators: CBS (CBS) news anchor Katie Couric, NBC anchor Brian Williams and ABC’s George Stephanopoulos.

Some MediaMemo readers have asked me to reprint all of Bercovici’s story, but I don’t have access to it. I can tell you, however, that is a very short story–maybe three or four paragraphs long–and that the text I quoted yesterday was the most interesting part. Here it is again:

Couric shed some light on her preparation for the interviews: Beforehand, she sought advice from former senator Sam Nunn and Council on Foreign Relations president Richard Haas. They told her to draw Palin out on her geopolitical worldview and urged her to let the governor speak at length without interrupting her. Maybe she should bring them along with her when she takes over at Meet the Press?”

Meanwhile, Quadrangle really has bigger problems on its mind these days than unauthorized blog posts. It is shutting down its media hedge fund after sustaining losses of 25 percent year-to-date.

So who said what at Quadrangle’s Foursquare conference, and was any of it interesting?

You got me. The media and tech confab is off the record. And so far, the members of the fourth estate who attended the event yesterday seem to be keeping their mouths shut.

But I did talk briefly with an attendee, who told me that the most interesting panel was the one that Portfolio’s Matt Cooper conducted this afternoon with television personalities Katie Couric, Brian Williams and George Stephanopoulos.

That would be an interesting group under any circumstance, but even more so since Couric’s interview of Republican VP candidate and Alaska governor Sarah Palin for CBS (CBS) is now considered to be a turning point in the 2008 election.

And while Couric hasn’t talked publicly about the interviews yet, she apparently did dish a bit today, according to a source who talked to Portfolio.com’s Jeff Bercovici:

Couric shed some light on her preparation for the interviews: Beforehand, she sought advice from former senator Sam Nunn and Council on Foreign Relations president Richard Haas. They told her to draw Palin out on her geopolitical worldview and urged her to let the governor speak at length without interrupting her. Maybe she should bring them along with her when she takes over at Meet the Press?”

UPDATE: Bercovici’s report has been pulled. Details here.

One newsworthy item not covered in Bercovici’s account: After the event, Couric gave Twitter correspondent MC Hammer a smooch, which was apparently well-received.
